Web-Only Radio: Networks and Stations Many internet radio stations exist only on the web Cost Comparison:

Cyberstation vs. Conventional Over-the-Air Station $10K vs. > $250K

Other than cost, why? No legal licensing or insurance requirements The internet is totally unregulated and as such internet radio is

unsanctioned by government rule

Audio-on-Demand Transforms the internet into a music

marketing Mecca Most major record labels support and

influence the use of the internet as a major source for “free” music to the public Great marketing tool Studies show record sales climb exponentially

when certain clips are pre-released on the Web.

The music industry and RealAudio influence on the net. With increasing speed and accuracy, combined

with streaming technology, the music industry is concerned about piracy.

Streaming technology is such that no file is ever copied, so music files are “temporary.”

There are ways to copy files “permanently,” but come on. . .you cant have your cake and eat it too. . .

Music Industry benefits from making audio available online

Internet Radio is not, like its counterpart, subject to ownership restrictions FCC regulates how many over-air stations can

be owned by any one company…not so for Web Radio.

Internet Radio is much less restrictive when compared with broadcast radio. You want to start a web radio station, start one:

No One Cares. . .

Internet Radio vs.. Broadcast Radio Both can be produced similarly, but with

one fundamental difference: Digitizing Digitizing: The process of converting analog

files into 1s and 0s in a digital file format. Encoding: storing a digital file in several

different formats, depending on the need for the digital output.

different formats, depending on the need for the digital output.

Encoding methods: Two basic types. . .

Use dedicated Hardware, called an Encoder. Limited functionality of resource (computer).

Use any computer with a Sound Card and appropriate software for file conversion

Encoding compresses large files so that memory allocation is considerably smaller than normal, allowing for ease of transfer over the network, and lessening download times.

Streaming Files are used in “real-time” but not stored digitally on the

client computer The server sends digital data in a continuous “loop” until

the client disengages it’s connection Uses Encoding and Reading technologies
